An efficient spline-based scheme on Shishkin-type meshes for solving singularly perturbed coupled systems with Robin boundary conditions
Kousalya Ramanujam, Vembu Shanthi
In this paper, we investigate a weakly coupled system of singularly perturbed linear reaction-diffusion equations with Robin boundary conditions, where the leading terms are multip…

A finite difference scheme for two-dimensional singularly perturbed convection-diffusion problem with discontinuous source term
Ram Shiromani, Niall Madden, V. Shanthi
We propose a finite difference scheme for the numerical solution of a two-dimensional singularly perturbed convection-diffusion partial differential equation whose solution feature…
